How can I get the exact platform type of mobile device from which the app is launched

[irigsoft]

Hello,

I am using a WebView and an Android app (Android 10) to run my app on a mobile device.

in this android app i am using javascriptinterface to call various procedures from my unigui app to android webview.

the problem is this:

1. In the Android app I create a setAndroidOptions function through which I control my mobile app settings from the unigui app.

2. on user login I call setAndroidOptions with specified options.

Everything works fine when used in my Android app (the WebView where the called javascript function exists), but if I call my app from a Google Desktop browser or a mobile browser, the app crashes when running unisession.AddJS('setAndroidOptions(options)' ) because this procedure exists in an android app (but not in google chrome or the mobile browser).

I'm trying to figure out what type UniApplication.UniPlatform is when I launch from the Android app, but when I launch it through a mobile device in a mobile browser, no uniplatform information is returned

  If (UniApplication.UniPlatform  <> [upDesktop])
  AND (UniApplication.UniPlatform  <> [upMobile])
  AND (UniApplication.UniPlatform  <> [upPhone])
  AND (UniApplication.UniPlatform  <> [upTablet])
  AND (UniApplication.UniPlatform  <> [upAndroid])
  AND (UniApplication.UniPlatform  <> [upiPhone])
  AND (UniApplication.UniPlatform  <> [upiPad])
  AND (UniApplication.UniPlatform  <> [upiPod])
  AND (UniApplication.UniPlatform  <> [upiOS])

 

I need to call unisession.AddJS('setAndroidOptions(options)') only when the app has started the session from my android app
If the session is started from a mobile or desktop browser, unisession.AddJS('setAndroidOptions(options)') should not be called. Is there a way to find out which application started the session

I use unigui Professional version.

This is my code in MainModule

...

    function  DetectPlatform():string;
    function  DetectDeviceType():string;
    function  DetectOperationSystem():string;
    function  DetectModel():string;

  public
    { Public declarations }
    uPlat: TUniPlatforms; // uniGUITypes

...

procedure TUniMainModule.UniGUIMainModuleCreate(Sender: TObject);
uPlat:= UniSession.UniPlatform; 

...

function TUniMainModule.DetectDeviceType: string;
begin
  if (upPhone in uPlat) then
     Result := 'Phone'
  else if (upTablet in uPlat) then
    result := 'Tablet'
  else if (upDesktop in uPlat) then
    result := 'PC';
end;

function TUniMainModule.DetectModel: string;
begin
  if (upiPad in uPlat) then
    Result := 'iPad'
  else if (upiPod in uPlat) then
    Result := 'iPod'
  else if (upiPhone in uPlat) then
    Result := 'iPhone'
  else if (upAndroid in uPlat) then
    Result := 'Android' //  Mobile Device
  else if (upDesktop in uPlat) then
    Result := 'Desktop'; //  PC
end;

function TUniMainModule.DetectOperationSystem: string;
begin
  if (upAndroid in uPlat) then
    Result := 'Android'
  else if (upiOS in uPlat) then
    Result := 'iOS'
  else if (upDesktop in uPlat) then
    Result := 'Desktop OS';
end;

function TUniMainModule.DetectPlatform: string;
begin
  if (upDesktop in uPlat) then
    result := 'Desktop'
  else if (upMobile in uPlat) then
    result := 'Mobile';
end;

thank you Andy but my problem is that when I run my app from webview I don't actually get information about uniPlatform it doesn't fall into any of the possible values I don't know why

The very first thing that is created by a UniGUI connection is the MainModule Session, surely the uPlat variable is seeded on MainModule.Create ?

You used "uPlat:= UniSession.UniPlatform;" to get uniPlatform but in my case uniPlatform has no value or the value is not in the possible values (I check them one by one)

[andyhill]

UniGUI source code:-

TUniPlatform = (upDesktop, upMobile, upPhone, upTablet, upAndroid, upiPhone, upiPad, upiPod, upiOS);

I develop mostly in standalone server mode and debugging a MainModule Create UniPlatform variable has never failed me ?

I guess I leave this with Sherzod or Farshand or Others - sorry it did not work for you - I would be interested to know why.

thank You for Your try, what is different between uniAndroid and uniMobile. I know the list TUniPlatform = (upDesktop, upMobile, upPhone, upTablet, upAndroid, upiPhone, upiPad, upiPod, upiOS), and try all possible values to get what kind is webView on Android app ( i guest that are uniAndroid or uniMobile  but they dont ).

I use StandAlone app, start session on webview in Android (or mobile browser) and uniPlatform is not in list (upDesktop, upMobile, upPhone, upTablet, upAndroid, upiPhone, upiPad, upiPod, upiOS)

i try to get uniPlatform by this way:

If (UniApplication.UniPlatform  = [upDesktop])
  OR (UniApplication.UniPlatform  = [upMobile])
  OR (UniApplication.UniPlatform  = [upPhone])
  OR (UniApplication.UniPlatform  = [upTablet])
  OR (UniApplication.UniPlatform  = [upAndroid])
  OR (UniApplication.UniPlatform  = [upiPhone])
  OR (UniApplication.UniPlatform  = [upiPad])
  OR (UniApplication.UniPlatform  = [upiPod])
  OR (UniApplication.UniPlatform  = [upiOS])

I expect to get uniAndroid or upMobile but don't.

Did you initialise the variable

procedure TUniMainModule.UniGUIMainModuleCreate(Sender: TObject);
begin
  uPlat:= UniSession.UniPlatform;

Thanks, Your way works.

But that's not enough because I get Android on any mobile device, whether it's a mobile browser or a web view. my solution is: i added a specific variable in the mobile url that uses the webview
